Introduction
DESCRIPTION
The ST-10 is a pressureless steam cooker consisting of
two independently controlled compartments enclosed in
a single cabinet. Each compartment is equipped with a
separate three-piece door with inner gasket plate isolated from the exterior surface. Door latches operate by
slam action for positive sealing of inner door. Steam and
steam-condensing circuits are electrically controlled. Operating controls are displayed on a single front-mounted
panel and include separate timers with indicator lights for
selection of constant steam or 60-minute-long duration
cooking.
A separate steam source required for operation of the
Pressureless Cooker is normally purchased with it, please
refer to the respective manual for guidance.
BASIC FUNCTIONING
The Model ST-10 may be operated with only one compartment in use; or both may be used simultaneously. Each
compartment is equipped with identical controls, allowing
selection of constant steam or 60-minute timer operation.
The cooker becomes operational when it is set to constant steam, or the timer is set at the desired cooking time
and the compartment door is closed. The indicator light
comes on and the steam solenoid valve opens, allowing
steam to ow into the compartment.
When steam owing inside the compartment has raised
the interior temperature to 195°F, the contacts of a thermostatic switch automatically close, completing the circuit
to the timer motor and starting the cooking time period. At
the end of the set interval, timer contacts switch to shut
off the cooking operation and sound a signal buzzer. The
buzzer is silenced by returning the timer dial to the OFF
position. In the constant steam mode, operation will be
continuous.
Steam emitted from the compartment along with liquid
cooking drainage is directed through a drain screen inside
the compartment into the cooker drain line. A cold water
solenoid valve connected into the cooker drain line is automatically actuated by a thermostatic switch in the boiler
drain to condense the steam to water prior to discharge
into the boiler drain.
SERVICE
Required service, both preventive and corrective, is explained in Section 6. Should repairs be required, a net-
work of authorized agencies is available to assist with
prompt service. A current Directory of Authorized

OPERATION WILL BE BY:
Electrically powered, A.S.M.E. constructed and National Board
Registered, 15 PSI (1 kg/cm2) steam boiler rated at 24kW, additional
ratings available as an option
NOTE: The only available space to supply utilities to the boiler is the 6”
(152mm) space between the floor and the cabinet base. PVC & CPVC
Pipe are not acceptable materials for drains.
CAUTION: REMOTE KETTLE OPERATION If this boiler is feeding a
remote kettle that will be more than 5 feet (1.5 meters) away, consult
factory before ordering.
WATER SUPPLY
Good quality water feed is the responsibility of the owner. Water quality
must be within the following general guidelines.
TDS: 40-125 ppm Hardness: 35-100 ppm Chlorine: <0.2 ppm
Silica: <13 ppm Chlorides: <25 ppm
Chloramine: <0.2 ppm pH: 7.0 - 8.5
The best defense against poor water quality is a water treatment system
designed to meet your water quality conditions.
